I was using 3.5.7 when it first started and I upgraded to 3.5.8 to see if that would help (it didn’t). I tried the config line you suggested anyway and there was no change.
With more testing, I found that changing the “From line” in the Campaign Content from Cathy HB cathyhb@mydomain.com to just cathyhb@mydomain.com actually allowed the campaign to send. The actual email account ‘noreply@mydomain.com’ is still being used as the actual sending and bounce address.
Source is below with a few edits for domain and IPs. I really appreciate any guidance here!

'Web-hosting email service included in cPanel is a common email hosting,
which allows you to send emails, manage email accounts through webmail and
email clients (Outlook, Thunderbird, Mail.app, .etc) via SMTP/POP/IMAP
connection/protocols.
That service is a good choice if you need to use a number of standard email
accounts.
All regular email service features are available for Namecheap Private
Email users as well. However, with the Namecheap Private Email, you can
also setup Exchange accounts to synchronize appointments, tasks, calendar
and email folders between your Namecheap Private Email account and
supported devices and email clients.’=20
